- SF Guiding frame
- Category：SF Guiding frame
- Abstract：They consist of a fixed base frame and a movable guide frame. The latter accommodates one or two positioning rollers and swivels round an imaginary pivot point on the infeed plane. When the feed path is deviated, the guiding roller frame is translated one side so that the material enters the correct set position at the next roller. Based on the working principle of the displacement correcting roller frame, the displacement correcting roller frame needs a sufficiently long feed span and discharge span.
